' I AGITATING AND'NI'IXING'APP'ARATUS.

1 iidllgphom it may.concermfl Be it known that I, 'LAMARTINE G. 'lREn'r,

trent, Placer county, State, of California, have invented certain new and useful Improvements in. Agitating and Mixing Apparatus; and I hereby declare the following to be a full,

- clear, and exact description of the same. I

The apparatus is designed for the agitating and mixing of liquidslimes, clay, cement, slurry,and sludge generally, the essential object of the invention being to provide a cheap,-

simple, and effective apparatus for the agitation, circulation, and mixing of the above-me'ntioned material, at the same time providing for the aeration of the pulp or material being treated. a v

To comprehend the invention, reference should'be had to theaccompanying sheetof drawings, wherein'- Figure 1- isa top plan view of the apparatus.

Fig. 2 is a cross-sectional view, inside -eleva-- tion, taken on line w a, Fig.-'1,ofthe drawings.- Fig. 3 is a broken detail View of the receiver with one of the distributerjandagitator-armsattachedthereto. 3 v

In the-drawings the numeral 1 isused to designate any suitableformof a receiving? tank, the size or diameter ofwhich is dependent on the work required. Within this receiving-tank is arranged a spider 2, which; is bolted or otherwise secured to the floor of the said tank. Said spider supports a reservoir 3, revolubly mounted thereon; To the upper end of the reservoir 3 is connected a short ex-' tension 4, which connects witha stuffing-box 5, secured to the dischargeend dofthe stationary feed-pipe 7 The connection between the extension 4 and the end of the feed-pipe 7 is such that the said extension 4 may turn,

or rotate freely withthe movement of the reservoir, which is driven as hereinafter exof the wall 13 the same is decanted, so to.

say, into the chamber 12. Hence the lighter ,SpecificationIof Letters Patent. 7

portion the material treated is drawn into the. circu'latingpu rnp. v a citizen of the United States, residing at Van Intothe reservoir 3, adjacent the bottomedge thereof, is screwed a series of" radial pipes 14, the outer ends of which are closed.

These pipesform radial arms, each arm being provided with a; series of tangential outlet openings 15, .through which the material forced into the radial arms makes its escape. In each outlet-opening is screweda short dis- 6-5 charge-.pipe16, which pipes depend from the radial arms and in addition to serving as discharge-fingers serve as stirrers for the material within the tank 1'. These fingers or stirrers gential discharge-fingers for the radial'arms. To'reduce-theoutlet area of the discharge of each a plug17, formed with a tapered or inclined :bore- 17'. -By thus reducing the outa let area of each discharge stirrer ,or fingerv a back pressurejis maintained within'the radial arms 14 and the reservoir 3, besides causing 3c the pulp passing through the radial arms to discharge. into the tank in the-form of finem l -i In operationthe naterial to be treated is fed; in; any suitable manner. into the tankl 85,

until it reaches the desired level. The pump t s. th n put i to. o e t drawing -1 terial-from the tank into thepumprchambef 8 and; forcing the same from I said chamber through the pipe7'intothe reservoir 3. As 9 the pressure in saidreservoir is increased by the material forced therein the same is forced therefrom into the hollow radial arms 14, es-' caping under-pressure from said arms through the tangentially-disposed depending discharge stirrers or fingers 16..This discharge is in the form of fine jet-streams, which discharge into or-impinge against the body of material within the tank, the radial arms 14 being submerged therein. disposition of the depending stirrers or fingers 16, an impelling action is imparted thereto,

due to the strains or recoil of the escaping jets, which is sufiicient to impart rotation to the radial arms and connected reservoir 3 in 5 a horizontal plane, causing the arms 14 and depending fingers or stirrers 16 to thoroughly agitate and mix the material or pulp within Y the tank 1. It will be understood that so extendto within a short distance-of the tanks 7 floor, andeach'stirrer or finger is set at an angle'to the horizontal, thus serving as tan stirrersor fingers, there is located in the end 75 Owing to the tangential long as thepump 9 is operating the body of 19 pulp or material within the tank 1 will be maintained in continuous circulation;

For the purpose of aerating the pulp'or' material circulating through the pump to the reservoir 3 an air-supplypipe 18* connects with the said pump 3. The suction created by thebody of material passing through the pump draws air into the pump through said pipe 18. The air thus admitted tothepumpintermixes with and thoroughly aerates the material being treated;- By means; of the valve 18 the quantity ofai-r' aduiitt'edthrough the pipe 18 may be regulated! The aeration of the material is essential wherethe same consists of a cyanidsolutio'n;
